CLOD-CRUSHER AND LAN D-LEVELER.

SPECIFTCATION forming part of Letters Patent No. 675,924, dated June 11,1901.

Application filed January 14, 1901. Serial No. 43,297. (NO modem T0 allwitamy it nur/y con/(187%:

Be it known that I, GEORGE E. BLAINE, a citizen of the United States,residing at (Joshocton, in the county of Coshocton and State of Ohio,have invented a new and useful Clod- Crusher and Land-Leveler, of whichthe following is a specification.

My invention relates to improvements in that class of clod-crushers andland-levelers in which drag-teeth and drag-bars are arranged to actalternately upon the soil to pulverize and smooth the same; and theobjects of my invention are to simplify and cheapen the construction, toprovide improved means for pivoting and adjusting the various drag-barsand tooth-bars, and to provide the device with certain new and usefulfeatures hereinafter more fully described,and partieularly pointed outin the claims.

My invention consists, essentially, in the means for yieldingly andadjustably connecting the various bars to the main frame, said meansbeing flexible rods attached to the bars and having coiled portionssurrounding pivot pins 01' lugs on the frame and extending upwardtherefrom, and means for adj ustin g and holding said upward extensionsconsisting of notched plates engaging the same, as will more fullyappear by reference to the accompanying drawings, in which- Figure 1 isa Vertical section of a device embodying my invention,taken on thebroken line of Fig. 2; and Fig. 2 is a plan view of the same.

Like characters refer to like parts in both figures.

A A represent the side beams, andB B the end beams, of a substantiallyrectangular frame, which is provided with stay-bolts F F to hold theframe together, to which bolts the draft means is attached.

O is a platform to aiford a seat-support and also to strengthen theframe. Beneath this frame and at regular intervals are a series oftransverse bars H, each alternate bar being wide enough to reach thesoil and act as a drag-bar to smooth the same and crush the clods, andthe other alternate bars are narrower and provided at the under sidewith drag-teeth to loosen and pulverize the soil. Each of the bars H isprovided near the inner side of the respective beams A with anupwardly-projecting flexible rod 4, rigidly attached to the bar ll atits lower end by means of a clip or other suitable fastening. Extendingupward, this rod is provided with a coil adapted to surround and rotatearound a pivot-pin E, projecting inward from the side of the beam A.This rod thence extends upward and engages a plate D, attached to theupper side of the beam A and provided with a series of recesses toengage and hold the rod 4. By the described means the bars H are eachpivotally, yieldingly, and adj ustably connected to the frame, each barbeing independently adjustcd. ly detaching all the rods on the drag-barsfrom the corresponding plates D these drag-bars can be thrown out ofaction and the drag-teeth only used, or in like manner the dragteeth maybe thrown out of action and the drag-bars only used, or by adjusting therespective rods of the respective series of bars the drag-teeth anddrag-bars may be adjusted relatively to each other as occasion requires.

By means of the simple, durable, and effective structure shown I am ableto produce a desirable article cheaply and furnish the same at less costthan the structures heretofore made for like purposes. It will also beobserved that the device is readily taken apart for storage or shipmcnt,it only being necessary to remove the bolts F F and detach the platformQ. The beams A and B are then readily separated and the rods 4 detachedfrom the pins and plates.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination of a frame, flexible rods pivotally attached to theframe near the middle of the rods, bars attached to the fiexible rods,and means for independent angular adjustment of the rods, substantiallyas described.

2. The combination of a frame, pivot-pins on the frame, flexible rodshaving coils surrounding and rotating on the pins, bars attached to therods, and means for angnlar adjustment of the rods on the pins,substantially as described.

3. The combination of a frame, pivot-pins in the frame, flexible rodshaving coils engagin g the pins and rotative thereon, and also extendingoppositely from the eoils, bars attaehed to the lower ends of said rods,and means for adjusting the upper ends of the rods, substantially asdeseribed.

4. The combination ofa frame having pivotpins, rods having eoils nearthe middle and engagin0` the pivot-pins, transverse bars attaehed to thelower ends of the rods, and notehed plates on the frame and engaging theupper ends of the rods, suhstantially as deseribed.

5. The combination of a frame having separable side and end beams,removable tiebolts in the end beams, pivot-pins in the side beams, rodshaving eoils detachahly engaging the pivot-pins, plates on the sidebeams having notehes detaehably engaging the rods, and transverse barsattaehed to the rods, substantially as deseribed.

6. The combination of a frame, a series of alternate wide and narrowtransverse hars,

teeth in the narrow bars, pivot-pins on the frame, flexible rodsattaehed to the bars and having eoils rotative on the pins, and meansfor independently adjusting the rods conneeted to the respective Wideand narrow bars, substantiaily as deseribed.

7. The combination of a frame having end beams and side beams, tie-boltsdetaehably seeuring the said beams, inwardly-projeeting pins and notchedplates on the side beams, alternate wide and narrow transverse barsbeneath the frame, drag-teeth in the narrow bars, fiexible rods attaehedto the bars and having eoils rotatively engaging the pivotpins, saidrods also engaging the notehes in the plates, snbstantially asdeseribed.
